Application filed October 30, 1922. Serial No. 597,883.

To all whom it may comem:

Be it known that I WmmArr S. Oscooo, Jr. a citizen of the -nited States, and a resldent of Chicago, in the county of Cook a and State oflllinois, have invented a new and useful Improvement in Wringer Attachments, of which the following is a full, clear, and exact description.

invention relates to improvements in w wringer attachment and it consists 1n the combinations, constructions, and arrangements herein described and claimed The principal object of my invention 18 to provide a device to prevent accidents to opw erators of, and increase the efliciency of, power clothes 'wringers, that can beeasrly attached to all ordinary types of wrmgers. A further objectvof my invention is to provide a device of the type described that W is adapted to be used on various sizes of wringers and in which the feed belt maybe adjusted vertically by shifting the entire device upon the wringer, an advantage which is not found in the ordinary type of fit feed belt that is permanently attached to the wrin er.

A rther object of my invention is to provide a device of the type described in which a guide member is provided for precluding ae lateral movement of the belt when in operation.

A ;further object of my invention is to providea device of the type described having a clamping means for securing the atm tachment to a wrin or that is adjustable for wringer frames various widths, which clamping means is so arranged as to distribute equal portions of the attachment on either side of the wringer. to Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims. y invention is illustrated in the accomca panying drawings forming part of this application, in which- Figure 1 is a side elevation of an embodiment of my invention applied to a wringer partially in cross section, co Figure 2 is a top lan view of the mechanism illustrated in igure 1, and

Figure 3 is an end elevation of the belt guide plate.

n carrying out my invention, I make use of an ordinary type of clothes wringer having a fram 1 and a pair of normally contacting rubber rollers 2 and 3. A spring 4i mounted upon the frame 1 serves to hold the rollers2 and 3 into close yielding contact with one another, and a compremion spring regulated by means of thumb screws 5. The wringer 1 1s further provided with a drip board 6, and with side boards 7 and 8 on either side of the roller 3.

My attachment for the wringer consists in a pair of side frames 9 and 10 each of which have a substantially horizontal portion 11 and downwardly inclined portions 12 and 13 at either end of the portions 11. The portions 11 and the portions 12 and 13 are in substantially arallel plane. The entire side frames 9 and 10 are made of a flat strap iron preferably, which is light and not likely to break.

The side frames 9 and 10 are supported in substantiallyparallel relation with one another at a predetermined distance by means of wooden rods 14: and 15. These rods 14': and 15 besides serving as means for holding the side frames 9 and 10 in fixed relation one to another serve as safet guards in the manner hereinafter described:

A pair of idler rollers L8 and 17 are rotatively supported in parallel relation to one another at the outer ends of the portions 12 and 13 of the side frames 9 and 10 respectively. The idler rollers 16 and 17 are larger than the rubber rollers 2 and 3 so that when the lower side of rollers 16 and 17 and 3 are on a level, the proper position, the upper side of the belt 18 will have enough upward slant away from the wringer rollers 2 and 3 to prevent any water squeezed out of the clothes from following the belt out too far to be caught by the drain board 6 and drained back into the tub.

A conveyor belt 18 of canvas and laced together at its opposite ends 19 by means of a lacing 20 is supported upon the idler rollers 16 and 17 and a portion thereof may be passed between the rollers 2 and 3 when the ends 19 are apart from one another before the lacing 20 is applied. It should be understood at this time that in applying the attachment to the wringer it is necessary of course, to unfasten the lacing 20 and. pass the conveyor belt 18 between the rollers lti 2 and 3 and subsequently refasten the lacing 20 so that the ends 19 will be bound to gether..

It has been my observation that conveyor belts which are alleged to operate successfully between rollers of the character of the rollers 2 and 3 have a constant tendency to move laterally, especially when an object such as clothes or the like pass between the rollers 2 and 3 or their equivalent. This lateral shifting of the belt 18 causes a reat deal of trouble in both the binding the belt 18 with the inner sides of the frame 1 or its equivalent or the tendency of the belt to entirely shift from one side of the idler rollers to the other end. In my present invention I have entirely precluded accidental lateral motion of the belt by the rovision of a smooth yet efiective guide p ate 19. The guide plate 19* is ordinarily made of zinc and consists in a tubular member adapted to permit the passage of the .belt 18 therethrough. The upper portion 20' of the tubular guide member 19 is relatively long, while the under portion is relatively short. Both the .portions 20 and 21 are upturned slightl at their outer ends to obviate the acci ental engagement of the fabric of the belt 18 therewith, which might tear the fabric if the edges were sharp. he guide member 19 is supported by means of a pair of connecting rods 22 which are pivotally mounted at one end 23 to the lower portions of the side members 9 and respectively, and at their opposite ends to an integral rolled sleeve 24 formed of an upturned rolled portion of the upper side of the tubular guide member 19.

The guide member 19 extends out beyond sideboards 7 and 8 and prevents any wear that might be caused by the slight upward ull of the lower loop of the belt against I and 8. On the types of wringers having no sideboards extending down below bottom of roller 3 the lower side of the idler rollers 16 and 1 being on a level with lower side of roller 3 there is no upward ressure of belt, so no friction. Being hinge in two places at 23 and at 24, it is self adjusting and goes into place as the frame is lowered over to of wringer, and is automatically centered by lacing the belt. The guide does not interfere with the drain board and works equally well with the wringer running in either direction.

Means for clampin the device upon the wringer 1 is provide in a pair of T-irons 25 and 26 disposed in substantially parallel relation with the rods 14 and 15. These T-irons 25 and 26 have threaded coaxial openings transversely disposed through their opposite ends, and are received u on opposite portions 27 and 28 respective y of bolts 29. The ends 27 of the bolts 29 are provided with right-hand threads, while the amie ends 28 are provided with left-hand threads so that when the bolts 29 are turned by means of a wing portion 30 integral there with, the 'T-irons 25 and 26 will be moved toward or away from one another depending the device over the wringer 1 in the manner shown in Figure 1.

"While lowering the frame over the wringer, the guide 19 with'o'ne end of the belt 18 through it, is inserted in the 0 en space between lower roller 3, or sideboar 7 and 8 and drain board 6. I

I next tighten the bolts 29 by means of the wing portions 30 so that the clam ing means or ll-shaped irons 25 and 26 tig htly engage with the frame 1, having first made sure that the rollers 16 and 17 are in their desired relation with the rollers 2 and 3.

I then thread the belt 18 between the rollers 2 and 3 and bring the other end up over the roller 17 and draw the ends 19 together with lacing 20 and the device is ready for use.

In use the'clothes such as indicated at 31 may be placed upon the belt 18, which, of course, will move with the rollers 2 and 3, and effectively feed the clothes or articles through the rollers, or, in fact, between the roller 2, and the belt 18 which is disposed around the roller 3.

The clothes or articles 31 will not tend to wrap about the roller 3 since that would be impossible because of the presence of the belt and they would not tend to wraparound the upper roller 2 as the pressure of the rollers 2 and 3 when squeezing out the water, presses the clothes into the coarse weave of the canvas belt, making the belt and clothes as one piece of cloth so the clothes stick to the belt, and have no tendency to turn up and wind around the smooth surfaced upper roller. The belt turning downward as it goes over roller 16 breaks the belt from the stiffened clothes which have no tendency to follow the belt any further, and clothes drop down into basket .or tub.

The guide member 19 which has been described serves to maintain the belt 18 at its proper position midway betwen the ends of the frame 1 and the rollers 2 and 3. Therefore there is no tendency to deliver the clothes or articles toward the ends of the rollers where they might become engaged or torn thereon by the accidental dripping through of the articles in the event the belt 18 was shifted entirely to one end of the rollers 2 and 3.

The proportions are such that, the rods 14 and 15 and the T-ir'ons and 26, and the side frames 12 and 13 leave no openings between them large enough for the operator to get her hands close to the wringer rolls 2 and 3, so accidents are practically impossible.

I claim:

1. The combination of a wringer having frame and a pair of normally contacting wringer rollers, of a supportng frame, means for removably clamping said supporting frame on said wringer frame, said means comprising a pair of oppositely disposed clamping irons arranged to be moved toward and away from each other by turn bolts having left and right-handed threads at their opposite ends respectively, a pair of idler rollers carried by said supporting frame, a belt adapted to pass between said wringer rollers and'over said idler rollers at its outer ends, means for fastening the opposite ends of said belt together to form an endless belt, and a guide member pivotally supported by said frame and adapted to engage with said belt, whereby said belt is prevented from movement laterally.

2. The combination with a wringer having a frame and a pair of normally contacting Wringer rollers, of a supporting frame, means for removably clamping said supporting frame on said wringer frame, said means comprising a pair of oppositely disposed clamping members, a pair of bolts having left and right handed threads on their opposite ends respectively, rotatably mounted on said supporting frame, said clamping members being provided with threaded openings therethrough and disposed on said threaded bolts, whereby rotation of said bolts may cause the clamping members to be moved toward and away from each other, and means carried on said supporting frame and associated with said rollers for conveying articles of clothing and the like through said rollers.
